My understanding is PCs are not very effective with anemones.

If you want to try to find a new home to save your bubble tip, you should probably post in the for sale or trade section. You might get more traffic in those areas. We have 4 already, so there is no room at this inn.

Clowns will often host in other things, easier to keep that anemones. We have seen them host in things like torch corals, frogspawn, and even star polyps. Just make sure the coral is big enough to not be killed by all the clown lovin..
You might even be able to make a trade for something in exchange for the struggling anemone.
